RWD based IDS for MANET
Kavita Varule, Sachin Bojewar · International Journal of Computer Applications · 2015
Mobile Ad-Hoc network (MANET) is a temporary infrastructure less network.This network is formed by combining some set of wireless mobile hosts [1] [5].The host is called as a node which dynamically establishes their own network.Intrusion detection in MANETs, however, is challenging for a number of reasons.These networks change their topologies dynamically due to node mobility; lack concentration points where traffic can be analyzed for intrusions; utilize self-configuring multi-party infrastructure protocols that are susceptible to malicious manipulation; and rely on wireless communications channels that provide limited bandwidth .To overcome these constraints, researchers have proposed a number of intrusion detection approaches specifically for MANETs.Intrusion detection is a process of identifying and responding to malicious activity targeted at computing and networking resources.In this IDS architecture multilayer specification based detection engine is used along with Random Walker Detector (RWD) [1] [16].It randomly traverses a network and find outs that on which node which attack is occurred.If there is attacks it performs re-routing.
